Penetration technique used to facilitate alternating utilization of two female partners vaginal and anal areas.
First female is in the "doggy style" position. Second female is laying on top of the first female in a back to back position. The order from the bottom up will be vagina, anus, anus, vagina. Stoplighting involves penetrating one hole and alternating to another to create a stoplight effect.
